What URL did you use? What is your data like?
I tried your exact config but with the field name of "name" rather than
spell_check, using the Solr 4.0 example. Then I added the following data:
curl http://localhost:8983/solr/update?commit=true -H
'Content-type:application/csv' -d '
id,name
sug-1,aardvark abacus ball bill cat cello
sug-2,abate accord band bell cattle check
sug-3,adorn border clean clock'
Then I issued a suggest request using curl and got the expected response:
Jack Krupansky@JackKrupansky ~ $ curl
"http://localhost:8983/solr/suggest?q=b&indent=true";
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<lst name="spellcheck">
<lst name="suggestions">
<lst name="b">
<int name="numFound">5</int>
<int name="startOffset">0</int>
<int name="endOffset">1</int>
<arr name="suggestion">
<str>ball</str>
<str>band</str>
<str>bell</str>
<str>bill</str>
<str>border</str>
</arr>
</lst>
<str name="collation">ball</str>
</lst>
</lst>
</response>
So, try that simple example first and make sure it works for you, then see
what else is different in your failing scenario.

Hi,
I'm currently working with SOLR 4. I tried calling my suggester feature and
got the error below:
5001java.lang.NullPointerException at

My suggest searchcomponent and request handler are as below:
<searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
<str name="name">suggest</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str
name="lookupImpl">org.apache.solr.spelling.suggest.fst.FSTLookup</str>
<str name="field">spell_check</str>
<float name="threshold">0.005</float>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>
<requestHandler class="org.apache.solr.handler.component.SearchHandler"
name="/suggest">
<lst name="defaults">
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">suggest</str>
<str name="spellcheck.onlyMorePopular">true</str>
<str name="spellcheck.count">5</str>
<str name="spellcheck.collate">true</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
Can anyone point out what I'm doing wrong here?
Thanks
